The advisory identifies a deserialization of untrusted data vulnerability in Delta DTM Soft. The affected product entry is Delta Electronics DTM Soft: <=1.6.0.0. The provided CVSS v3.1 vector is AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating local access and user interaction are relevant to exploitation, with potentially significant confidentiality, integrity, and availability impact. The vendor’s remediation is to update to the latest version available from Delta’s Download Center and review the vendor advisory Delta-PCSA-2025-00009.

Defensive priority

High. The issue is rated High (7.8) and affects software used in industrial/engineering environments. Priority should be highest for systems that process untrusted files or receive data from less-trusted sources, and for endpoints used to open or manage DTM Soft project or BIN files.

Recommended defensive actions

• Update Delta DTM Soft to the latest vendor-released version from Delta’s Download Center.
• Review and apply guidance in Delta advisory Delta-PCSA-2025-00009.
• Restrict use of affected systems to trusted users and trusted files only, especially where local file handling is involved.
• Limit exposure of engineering workstations and related assets using network segmentation and least-privilege access.
• Back up configuration and project data before updating, and verify compatibility after remediation.
• Monitor affected endpoints for unusual file-processing behavior or unexpected application crashes.
• Track CISA and vendor updates for any revised impact statements or remediation guidance.
